Abstract (en)
[origin: WO2016027181A1] A fault detection system (100) for detecting faulty devices among a first plurality of serviceable devices (200) is provided. The serviceable devices have a wireless transmitter (210) arranged to periodically transmit a wireless signal (230) that encodes a device identifier. Mobile devices have a receiver (310) arranged to receive the wireless signal of a serviceable device within the transmission range, and to obtain the device identifier from the wireless signal. A fault detector (400) is arranged to detect faulty devices by selecting device identifiers in the plurality of device identifiers for which no device identifier was received in a time period.
